Sensor Playground

Sensor Playground turns your phone into a live dashboard for DIY sensor nodes built on the ESP32 or a Raspberry Pi class single-board computer. Flash the free companion firmware onto your board, wire up a supported sensor, and the app finds the node automatically on your local network or via Bluetooth LE — no cloud, no account, no registration. Readings appear as clear cards and live charts, updated in real time. CONTINUOUSLY GROWING Development is ongoing: updates ship regularly, and support for new sensors is added continuously. If your favourite sensor is not on the list yet, chances are it will arrive in one of the next updates. HIGHLIGHTS • Automatic discovery of sensor nodes over Wi-Fi (LAN) and Bluetooth LE • Live cards and charts for every measured quantity • Air-quality rating derived from IAQ, CO₂ or eCO₂/TVOC readings • Dedicated screens for gesture, distance and contact sensors • Send bitmaps to an SSD1306 OLED display node • Signal-strength badge for Bluetooth nodes • °C/°F switch, English and German, screen-reader friendly • Everything stays on your own network: TLS-encrypted and API-key protected — no cloud involved SUPPORTED SENSORS (and counting) • Environment & air quality: BME680, BME280, SCD30, SGP30, MCP9808, SHT31, SHT41, AHT10/AHT20, CozIR-A • Light & optical: SI1145 (sunlight/UV), TCS34725 (color), analog light sensor • Motion & orientation: IMU 10DOF, MPU6050, MMA7660 • Infrared temperature: MLX90615 (non-contact) • Positioning: Air530 GNSS/GPS • Event-driven: PAJ7620 gesture, VL53L0X laser distance, button, hall sensor, magnetic switch, PIR motion, vibration • Display: SSD1306 OLED (128×64) GOOD TO KNOW • You need at least one sensor node: an ESP32 or a Raspberry Pi class board running the free, open companion firmware. Arduino sketches and Python scripts are available for every supported sensor. • A built-in simulated sensor lets you explore the app before any hardware is connected. • Scanning and discovery are free for all sensors. Data visualisation for a few selected sensors requires a one-time in-app licence purchase, which supports the ongoing development. Whether you are a maker, a teacher, a student or simply curious about the air in your room — Sensor Playground makes hardware experiments visible.

Verdict
The clearest difference is ads: Sensor Playground at none against InCode's shown. Sensor Playground also leads on update cadence (every 3 days vs weekly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. InCode sells 3 in-app purchases, starting at $2.49 per month and Sensor Playground sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
InCode ships an update weekly, Sensor Playground every 3 days. The most recent releases landed on October 5, 2026 and September 26, 2026 respectively.
